We’ve come a long way since our last blog post on Koruza real time (move) driver with many improvements made to the system, including the changes to the real-time driver itself. The new structure of electronics is much more fault tolerant because of the simplicity and task distribution. The Koruza move driver is now just a simple board dedicated to...
Effective iteration cycles are very important part of the development of a new device. By doing a new version/iteration of the product you can enhance it in many different ways, which was done very successfully with the Koruza electronics/embedded system. Koruza Pro is in this manner growing to become a high-grade robust industrial telecommunication system. The main advantage of the...
KORUZA is exhibiting at 4YFN 2017 in Barcelona! 4YFN, the growing tech startup community, is the business platform of Mobile World Capital Barcelona and this year’s event, the fourth in a row as part of the Mobile World Congress, will be held in Spain’s beautiful art and architecture capital from 27th February till 1st March. Connecting startups, investors and corporations...
The Koruza driver is an additional board to Koruza router. Its main task is to handle the real-time parts of Koruza system, like stepper motors for the laser beam positioning, infrared communication between two Koruza units, encoders for stepper motors, etc. The Koruza driver consists of the two separate PCB boards. First is the driver board. It is the main...
Optical wireless system KORUZA operates by directing a collimated beam of light towards another unit to establish communication. To be able to precisely aim a beam of light with a millimeter precision when shining at a distant unit at 150 m away, one requires two key components; a precise motor drive (see blog about it) for mechanical displacement of a...
KORUZA wireless optical system enables 1Gbps or 10Gbps communication with a collimated beam of light between two buildings. To interface and power the units, networking ports are required, we looked at a number of practices from various vendors. For throughputs up to 1Gbps the standard interface is wired RJ-45 ethernet. WiFi routers and other networking devices are often powered through...
For Koruza Pro we wanted to find a solution for the sealing, such that the units would be easy to assemble, use small part count and be cheap for manufacturing. Until the version 2.3.1 we used an independent internal supporting structure for the motorized alignment system and PCB supports, like shown in the picture 1. A rectangular, 2 mm thick...
We are interested in how our wireless optical system KORUZA operates in various environmental conditions and to better understand the signal loss mechanisms, we are conducting scientific experiments in our domain. Free Space Optical systems use visible or near IR wavelengths to wirelessly transmit data and are thus susceptible to ambient and weather influences that may cause temporal decrease in...
Our next generation device KORUZA Pro will enable a versatile construction of last-mile networks to people’s homes and thus deliver them a faster internet service. To best cover all the possible installation scenarios and provide a user friendly installation process, we are exploring and innovating on the mounting system. The mounting system needed to be smaller than the mount on...
Wireless optical system KORUZA and other FSO systems require that the units are pointed at each-other to be able to receive the collimated beam of light that transfers the data between them. Typically an infrared and invisible to the human eye beam is used and thus we can not simply see where one unit is pointing. To solve this, generally...
